Pipe diameter does not affect black powder distribution, erosion

Ehab Elsaadawy Abdelmounam Sherik Saudi Aramco Dhahran Pipe diameter seems to have no influence on black powder particles' velocity distribution in natural gas transmission pipelines operating at 10 m/sec and 20 m/sec, and there will be little, if any, particle-size segregation. Filter systems installed on such pipelines should be sized to collect the entire particle-size spectrum. A pipeline bend with longer radius of curvature (e.g., 3.0) will have more uniformly distributed erosion over the outer wall of the bend, making it a better candidate for applications in severe erosive service environments, such as black powder contamination. But black powder erosion even in bends of smaller ra...
